APPARATUS FOR SEPARATING PETROLEUM VAPORS.

SPECIFICATION forming part of Letters Patent No. 266,990, dated November'7, 1882. Application filed July 19, 1881. (No model.)

To all it whom may concern Be it known that LWILLIAM CARSON HALL, acitizen of the United States, residing at Oil City, in the county ofVenango and State of Pennsylvania, have invented certain new and usefulImprovements in Separators; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which IO it appertains to make anduse the same, ref

erence being had to the accompanying'drawings, and to letters or figuresof reference marked thereon, which form apartof this specification.

My invention relates to an apparatus for separating petroleum vaporsanddistillates and obtaining products of different specificgravities in refining petroleum; and it consists in attachingto thegoose-neck, at different heights thereon, two or more branches or pipesleading to a condenser, so that the lighter vapors shall seek and passthrough the higher branches and the heavier ones through the lower pipesor branches, and also in uniting the said high and low pipes at a pointbetween the gooseneck and the condenser and admitting steam into thepipes carrying the vapors, as will be hereinafter described inconnection with the drawings, and then pointed out in the claims.

In the drawings, Figure 1 represents a side view of my apparatus. Fig. 2is a side view of the same, with the addition of a small tank to receivegummy matter, and showing a slight modification in the arrangement ofthe pipes 5 through which steam is admitted in the apparatus. y

In said drawings, A represents a still; B,the upright outlet orgoose-neck thereof.

0, D, and E are horizontal pipes, connected at different heights to saidgoose-neck to lead the vapors from the upright pipe B toward acondenser, K. The pipes G and D are united by a short vertical pipe, F,and the pipes D and E are united by means of the pipe F G is asteam-pipe leading (in Fig. 1) a jet of steam into the upright Fadjacent to the point where it enters the pipe E, its object being tocarry over and prevent any vapors condensed in the fore part of the pipeE from running down into the pipe F and also helps to draw light vaporsup in pipes F and F The vertical connecting-pipe between the pipes G andD is for the purpose of letting light vapors pass up from the pipe 0 to'D and heavy or condensed vapors to pass down from the pipe D to the pipe0. These pipes O and D have traps H, provided with outlets for emptyingthem when not in use. These pipes are also connected with the verticalpipe L, used for drawing off the gum or thick products, &c., from theapparatus, and while this is done the stop-cocks c and din the pipes Uand D are closed.

Fig. 2 shows clearly the means for drawing off the gum through the pipeL. A steam-pipe, 6 5 O, admitting ajet of steam in the lower end of saidpipe facilitates the expulsion of the gum from the pipe L to the tank L.The pipe F in Fig. 2 is provided with a cock. P, that can be closed, andthe steam-jet is introduced into the apparatus through a coupling-jointunder said cock, and into the lower end of the pipe m, leading intothetop of the upper vapor-pipe,E.

ln usingthe apparatus constructed as shown in Fig. 2, when the vaporsstart to come over 7 from the still the cock lin pipe L and cook Pinpipe F are closed, while the cooks c and d in pipes O and D are leftopen and steam is gently admitted in pipe a. Light vapors ascend throughthe vertical pipe or goose-neck B to the pipe E, and also through thepipes O and D, F and m, and are condensed separately. The heavier vaporscoming after follow the pipe D to the condenser, and the heaviest "aporsfollow the pipe 0, and thus each gravity of vapors is condensedseparately. When using the apparatus to obtain paraftine from tar, thecooks c and d in pipes O D are closed, and the cock Zin pipe L isopened, and the thick and heavy products are drawn off through the pipe0 L into the tank L with the aid of the steamjet admitted through thepipe 0.

I'am aware that it is not new to use traps on outlet-pipes in thecondenser or after passing the condenser. Neither is it new to employ 5steam-jets between a first and second distillation, as such devices areshown in the patent to J. W. Oulmer, of July, 187-9, and others.

[am also aware that it is not new, broadly,

to separate a petroleum distillate in various Ioo gravities, as shown inpatent to J. H. Alexander, of June, 1880, and other patented apparatus.Nor is it new to take the vapors at different heights from the sidewalls of a still; but my construction differs from those heretoforeused, as well as the results obtained.

What I claim is 1, The combination of a sti1l,a vertical pipe, l3,secured to the top thereof, a series of pipes, O D E, connected atdifferent heights to the pipe B, and united together again at a distancefrom the still, with asteain-pipe connected with the uppermost pipe, E,cocks 0 d, and traps H, upon the lower pipes, O D, lead ing from thestill, substantially as and for the purpose described.

2. The combination of a still, a pipe, B, secured to the top thereof, aseries of pipes connected at different heights to the pipe B, and unitedtogether by means of a suitable pipe. L, with a tank, L, and steam-pipeO to lead ajet of steam toward said tank, substantially asand for thepurpose described.

In testimony whereof I affiX my signature in presence of two witnesses.

WILLIAM CARSON HALL.
